/**
 * run-yaml.ts
 *
 * Implements the pwpilot_run_yaml MCP tool.
 *
 * Execute a test directly from its YAML definition — no .spec.ts required.
 * The YAML test definition is a portable, self-describing file generated
 * alongside every test by pwpilot_save_test. It contains all the
 * information needed to run the test: locators (with fallbacks for healing),
 * actions, assertions, and timeouts.
 *
 * This tool accepts either:
 *   - testName: looks up <artifactsDir>/yaml/<testName>.yaml automatically
 *   - yamlPath: an explicit absolute path to any .yaml file
 *
 * Role in the overall flow:
 *   pwpilot_save_test → YAML file on disk
 *   pwpilot_run_yaml  → runYaml() → YamlExecutor.runFromFile() → YamlExecutionReport
